CYRUS HUNT, OF FAIRHAVEN, MASSACHUSETTS.

Laim 'Patent No. 84,189, dated November 17, 186s;-`

To allpersonsto 'whom these presents ma/y come:4

Be it known that I, CYRUS D. HUNT, of Fairhaven, in the county of Bristol, and State of Massachusetts, have invented a new and useful Improvement in Nail- Outting Machines; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Fignre 1 is a top viewand j Figure 2, a vertical and longitudinal section of my improved mechanism.

In such drawings, A may be supposed to represent a part ofthe frame of a nail-cutting machine.

The strip B of nail-plate, from which the nails are to -be cut, is required to have an intermittent advance movement, and to be revolved, with a reciprocating" made no description or representation of it.

1 At its rear end, the strip B is to be connected to lo1` heldin connection with a rod, C, and is to be supported within, and by two grooved guides, D D, extending 'om a. tubular shaft, E. The said shaft E, sustained in bearings or boxes a a, supported bya bent or rightangular vibratory arm, F, has a gear or range of teeth,

G, extended about it concentrically. This gear en` gages with a toothed sector, H, fixed to a shaft, I, arrangedin hearings, bb, applied to the vibratory arm.

On the lower end or part of the shaft I, isa bevelledgear or toothed sector, c, which engages with another such gear or sector, d,- xed upon a long horizontal rocker-shaft, e.

The juncture of the pitch-lines of the teeth of the two sectorsc d is to be in the. axis of motion of the vibratory arm F, in order that the two sectors may be in engagement with each other during the movement of such arm. i f p From the rocker-shaft e, an arm,-j, extends, and is jointed to the lower end of a rod, g, which depends from a crank-pin, h, extended from .a gear, I, Which engages with another gear, k. The two gears i, and k revolve on stationary centres or pins, lm, projecting from the frame A, and the gear k engages with a gear, n, fixed on a shaft, o, ofthe machine.

vA connecting-rod, p, pivoted to the vibratory arm F, whose centre of motion is shown at q, is applied to a crank-pin, fr, projecting from the gear k. By means of suchgear, crank-pin, and rod, the arm F, while the v pin is in revolution, will be vibrated so as to move the nail-plate away fromand down upon the. bed-die, in

order that such plate may be revolved one hundred and eighty degrees while being so moved.

The mechanism for revolving the plate or the tubular the toothed sectors ed, the shaft e, the'arm j, the con necting-rod g, the crankpin h, and the gear i.

. I claim the arrangement, as well as the combination, of the gears t k, their crank-pins h fr, the connectingrods g p, the arm f, rocker-shaft e, toothed sectors c d,

-shaft I, toothed sector H,and gear G, as applied to the Witnesses:
